Computer and web browser. Use a computer and a web browser to discover the
switch in your network and access the device UI of the switch:
Access the switch from a Mac or Windows-based computer using the NETGEAR
•
Switch Discovery Tool on page 14.
Set up a fixed IP address for the switch on page 15.
•
User Manual13Install and Access the Switch in
Your Network
Gigabit Ethernet Plus Switches
Access the switch and discover the IP address of the switch
By default, the switch receives an IP address from a DHCP server (or a router that
functions as a DHCP server) in your network.
For information about setting up a fixed (static) IP address on the switch, see Set up a
fixed IP address for the switch on page 15.
Access the switch from a Mac or Windows-based computer using the NETGEAR Switch Discovery Tool
The NETGEAR Switch Discovery Tool (NSDT) lets you discover the switch in your network
and access the device UI of the switch from a Mac or a Windows-based computer.
To install the NSDT, discover the switch in your network, access the switch, and
discover the switch IP address:
1. Download the NSDT by visiting
netgear.com/support/product/netgear-switch-discovery-tool.aspx.
Download either the Mac or Windows version.
2.
Temporarily disable the firewall, Internet security, antivirus programs, or all of these
on the computer that you will use to configure the switch.
3.
Unzip the NSDT files, double-click the .exe or .dmg file (for example,
NETGEAR+Switch+Discovery+Tool+Setup+1.2.102.exe or
NetgearSDT-V1.2.102.dmg), and install the program on your computer.
Depending on your computer setup, the installation process might add the NETGEAR
Switch Discovery Tool icon to the dock of your Mac or the desktop of your
Windows-based computer.
4. Reenable the security services on your computer.
5. Power on the switch.
The DHCP server assigns the switch an IP address.
6. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection. The computer and the switch must be on
the same Layer 2 network.
7. Open the NSDT.
User Manual14Install and Access the Switch in

shows the IP address that is assigned to the switch.
Tip: You can copy and paste the IP address into a new shortcut or bookmark it for
quick access on your computer or mobile device. However, if you restart the switch,
a dynamic IP address (assigned by a DHCP server) might change the IP address, and
the bookmark might no longer link to the login page for the switch. When you restart
the switch, you must repeat this procedure so that you can discover the new IP
address of the switch in the network and update your bookmark accordingly. You
can also set up a fixed (static) IP address for the switch (see Set up a fixed IP address
for the switch on page 15 ) to make sure that the new bookmark always links to the
login page for the switch, even after you restart the switch.
Set up a fixed IP address for the switch
By default, the switch receives an IP address from a DHCP server (or a router that
functions as a DHCP server) in your network. However, the DHCP server might not always
issue the same IP address to the switch. For easy access to the switch device UI, you can
Your Network
User Manual15Install and Access the Switch in
Gigabit Ethernet Plus Switches
set up a fixed (static) IP address on the switch. This allows you to manage the switch
anytime from a mobile device because the switch IP address remains the same.
To change the IP address of the switch, you can connect to the switch by one of the
following methods:
Through a network connection. If the switch and your computer are connected to
•
the same network (which is the most likely situation), you can change the IP address
of the switch through a network connection (see Set up a fixed IP address for the
switch through a network connection on page 16).
Through a direct connection. In the unlikely situation that the switch is not connected
•
to a network, or for some reason you cannot connect to the switch over a network
connection, you can change the IP address of the switch by using an Ethernet cable
and making a direct connection to the switch (see Set up a fixed IP address for the
switch by connecting directly to the switch off-network on page 17).
Set up a fixed IP address for the switch through a network connection
If the switch and your computer are connected to the same network (which is the most
the likely situation), you can change the IP address of the switch through a network
connection.
To disable the DHCP client of the switch and change the IP address of the switch
to a fixed IP address by using a network connection:

Set the quality of service mode and port rate limits
You can manually set the Quality of Service (QoS) modes to manage traffic:
Port-based QoS mode. Lets you set the priority (low, medium, high, or critical) for
•
individual port numbers and lets you set rate limits for incoming and outgoing traffic
for individual ports. If broadcast filtering is enabled, you can also set the storm control
rate for incoming traffic for individual ports.
802.1P/DSCP QoS mode. Applies pass-through prioritization that is based on
•
tagged packets and lets you set rate limits for incoming and outgoing traffic for
individual ports. If broadcast filtering is enabled, you can also set the storm control
rate for incoming traffic for individual ports.
This QoS mode applies only to devices that support 802.1P and Differentiated
Services Code Point (DSCP) tagging. For devices that do not support 802.1P and
DSCP tagging, ports are not prioritized but the configured rate limit is still applied.
You can limit the rate of incoming traffic, outgoing traffic, or both on a port to prevent
the port (and the device that is attached to it) from taking up too much bandwidth on
the switch. Rate limiting, which you can set for individual ports in either QoS mode,
simply means that the switch slows down all traffic on a port so that traffic does not
exceed the limit that you set for that port. If you set the rate limit on a port too low, you
might, for example, see degraded video stream quality, sluggish response times during
online activity, and other problems.
Use port-based quality of service and set port priorities
802.1P/DSCP is the default QoS mode on the switch, but you can also set port-based
QoS.
For each port, you can set the priority and the rate limits for both incoming and outgoing
traffic:
Port priority. The switch services traffic from ports with a critical priority before traffic
•
from ports with a high, medium, or low priority. Similarly, the switch services traffic
from ports with a high priority before traffic from ports with a medium or low priority.
If severe network congestion occurs, the switch might drop packets with a low priority.
Port rate limits. The switch accepts traffic on a port at the rate (the speed of the
•
data transfer) that you set for incoming traffic on that port. The switch transmits traffic
from a port at the rate that you set for outgoing traffic on that port. You can select
each rate limit as a predefined data transfer threshold from 512 Kbps to 512 Mbps.

Use 802.1P/DSCP quality of service
In the 802.1P/DSCP QoS mode, the switch uses the 802.1P or DSCP information in the
header of an incoming packet to prioritize the packet. With this type of QoS, you cannot
control the port prioritization on the switch because the device that sends the traffic
(that is, the packets) to the switch prioritizes the traffic. However, you can set the rate
limits for individual ports on the switch.
The switch accepts traffic on a port at the rate (the speed of the data transfer) that you
set for incoming traffic on that port. The switch transmits traffic from a port at the rate
that you set for outgoing traffic on that port. You can select each rate limit as a predefined
data transfer threshold from 512 Kbps to 512 Mbps.
To use 802.1P/DSCP QoS mode and set the rate limits for ports:

Manage broadcast filtering and set port storm control rate limits
A broadcast storm is a massive transmission of broadcast packets that are forwarded
to every port on the switch. If they are not blocked, broadcast storm packets can delay
or halt the transmission of other data and cause problems. However, you can block
broadcast storms on the switch.
You can also set storm control rate limits for each port. Storm control measures the
incoming broadcast, multicast, and unknown unicast frame rates separately on each
port, and discards the frames if the rate that you set for the port is exceeded. By default,
no storm control rate limit is set for a port. You can select each storm control rate limit
as a predefined data transfer threshold from 512 Kbps to 512 Mbps.
To manage broadcast filtering and set the storm control rate limits for ports:
1.
Open a web browser from a computer that is connected to the same network as the
switch, or connected directly to the switch through an Ethernet cable.

Set rate limits for a port
You can limit the rate of incoming (ingress) traffic, outgoing (egress) traffic, or both on
a port to prevent the port (and the device that is attached to it) from taking up too much
bandwidth on the switch. Rate limiting simply means that the switch slows down all
traffic on a port so that traffic does not exceed the limit that you set for that port. If you
